Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an adjustable base for a coiled scaffold. Background Art

Multi-story or high-rise cantilevered external scaffolding mostly adopts single-layer cantilever or multi-layer cantilever methods. Existing scaffolding generally adopts disc-type scaffolding. During the installation of cantilever steel beams, problems such as on-site construction may cause the installation positions of cantilever steel beams to be on different horizontal planes. The base of the existing disc-type scaffolding is directly fixed on the cantilever steel beam and cannot be adjusted, while the length of the scaffolding is standard, which leads to inconsistent heights of the scaffolding and affects the connection. Utility Model Content

[0007] Preferably, the adjustment seat is a cylindrical structure, the center of the adjustment seat is provided with a first threaded through hole threadedly connected to the screw rod, and the edge of the adjustment seat is evenly provided with handles for driving the adjustment seat to rotate around the screw rod. The handles are convenient for holding and rotating the adjustment seat.

[0008] Preferably, the top surface of the adjustment seat is provided with a plurality of annular limiting grooves, which are coaxially distributed with the first threaded through hole. The outer diameter of the scaffold has two or even multiple models, and the annular limiting grooves are used for end face positioning of the scaffold.

[0009] Preferably, a boss is fixedly provided at the inner end of the top surface of the handle, a second threaded through hole is provided on the boss, the axis of the second threaded through hole vertically passes through the axis of the first threaded through hole, and a bolt is provided in the second threaded through hole. After the lower end of the scaffold is supported by the adjustment seat and adjusted to a suitable height, the adjustment seat is connected and fastened to the scaffold by bolts, thereby limiting the lower end of the scaffold.

[0010] Preferably, a transverse slot hole is provided on the first connection part at the lower side of the stud, the limiter slides through the transverse slot hole, and the upper side surface of the inner end of the limiter is configured as an inclined surface; a plurality of limiter rods parallel to the stud are fixedly provided on the outer side of the first connection part, and a sliding hole corresponding to the limiter rod is provided on the second connection part. This connection method increases the connection reliability of the limiter.

[0011] Preferably, the nut is configured in two pieces, and a spring washer is arranged between the two nuts. The spring washer pre-tightens the two nuts to prevent the nuts from loosening, so that the limiting part is more stable.

[0012] Therefore, the utility model has the beneficial effects of stable and reliable connection and convenient adjustment. BRIEF DESCRIPTION OF THE DRAWINGS
